Question

Find the probability of an observation lying more than z = 0.5 standard deviations below the mean. Group of answer choices 0.3085 0.6915 0.1915 -0.50

Answer 1

Answer #1

Solution,

Using standard normal table

P( Z < 0.5 )

See the z-score 0.5 in standard normal corresponding the probability is = 0.6915'

P(Z < 0.5) = 0.6915
